, 19 Claims. (Cl. 297-232) I ABSTRACT OF THE DISCLOSURE There isdisclosed a foldaway seating arrangement for use in co-operation with anauditorium railing and the like, said arrangement comprising a platformhaving foldable legs, said legs being exten'clable to position saidplatform adjacent a lower run of said railing in the operative positionof said platform, seating means mountable on said platform, and railengaging means secured to said platform for engaging an upper run ofsaid railing to at least aid in suspending said platform from said upperrailing run in a foldaway stored position of said platform and saidseating means.

My present invention relates to foldaway seating platforms for use inauditoria, arenas and other places of large seated congregations, andmore particularly to platform arrangements 'of the character describedfor use in cooperation with the steel or'other type of railingconventionally provided in such auditoria and the like to define theaisles and seating sections thereof.

conventionally it has been the practice in the operation of auditoriaand the like, when unusually large crowds are anticipated, to providelarge numbers of folding chairs to accommodate the overflow crowd. Thefolding chairs usually are placed in the aisles of the auditoriumimmediately behind the railing usually provided to delineate suchaisles, particularly at the edges of balconies or other elevated seatingsection. Because the aisles usually are recessed considerably below theadjacent rows of permanent seats, temporary platforms are placedthereon, at convenient positions adjacent the railing so that thespectators in the temporary seating arrangements are seated at theproper elevation for'viewing the stage or the like over the heads of theaudience in front of them and over the railing itself. I

The installation and subsequent removal of these temporary platformswith the required folding chairs thereon involves considerable time,labor and expense, in addition to the fact that the temporary platformsfrequently become displaced from the railings by the press of the crowdspassing through the aisles so as to distort the temporary seatingarrangement and to block the remainder of the aisles. Moreover, thestoraging of the temporary platforms, which are relatively large andbulky, together with the folding chairs used therewith requiresconsiderable space and involves considerable expense not only in theprovision of the storagefacilities but also in the time and laborinvolved in .transporting the platforms and folding chairs to and fromthe place or storage.

I have-solved these problems by providing novel forms of foldawayseating arrangements. In one form, the elevated platform for the foldingchairs is provided with novel means both for temporary or permanentlysecuring the platform as desired to the aforementioned railing duringoperation thereof to prevent displacement of the platform from therailing. When not in use my novel platform is provided with additionalcooperating means for securing or suspending the unused platform againstthe railing for storage purposes in a position such that no appreciableobstruction is offered to the aisle adjacent the railing. In anotherarrangement of my invention the platform is provided with additionalnovel means for supporting the 3,394,963 Patented July 30, 1968 icechairs when folded in the stored position of the platform, such thatboth the chairs and the platforms can be mounted in stored positions onthose railing'sections at which the platforms are periodically used. Thelast-described arrangement of my invention wherein both the platform andthe chairs are stored in situ likewise offers no appreciable obstructionto the adjacent aisles.

In still another arrangement of my invention foldable seat means arefoldably or hingedly secured to each of the seating platforms, and thelatter are pivotally or otherwise secured to the auditorium railing insuch manner that both the platform and the folding seat means foldablysecured thereto can be moved between their stored and operativepositions with a minimum number of manipulations thereof, with theresult that the time for setting-up and storing the last-mentionedfoldaway seating arrangement is further reduced. The foldable seat meansis provided either in the form of discrete folding chairs or of acontinuous folding bench extending along the length of a given platform,with either the folding chair arrangement or the folding bench beinghingedly or otherwise foldably secured to the platform. When not in usethe platform with its folded seat means can be pivoted or otherwisemoved to a suspended, storaging position on that section of auditoriumrailing at which the seating platform is used for temporary seatingpurposes.

In my first mentioned foldaway seating arrangement the necessaryseparate storage space is considerably reduced inasmuch as the bulkiestpart of the seating arrangement, viz. the platforms, is stored at thelocation of their occasional use. In this case it is only necessary toconvey the folding chairs to and from the storage facilities therefor.In the remaining arrangements of my novel seating platform both theplatform and the chairs or bench used thereon are stored at the locationof their use so that the aforementioned storage facilities areeliminated altogether and likewise the necessity of conveying foldingchairs or the like to and from the locations of their use. In very largearenas or auditoria, such as are in use at the present-time, the savingsresulting from decreased labor and the elimination of costly storagefacilities for conventional temporary seating arrangements are veryconsiderable.

During the foregoing discussion, various objects, features andadvantages of the invention have been alluded to. These and otherobjects, features, and advantages of the invention, together withconstruction details thereof, will become apparent as the followingdescription of certain presently preferred embodiments of the inventionand certain presently preferred methods of practicing the same proceeds.

In the accompanying drawings I have shown certain presently preferredembodiments of the invention and have illustrated certain presentlypreferred methods of practicing the same in which:

FIGURE 7 is an end elevational view of the seating arrangement of FIGURE6;

FIGURE 8 is a partial isometric view showing the seating arrangement ofFIGURES 6 and 7 in its foldaway position; and,

FIGURE 9 is an end elevational view of the seating arrangement as shownin FIGURE 8.

Referring now more particularly to FIGURES 1 to 3 of the drawings, theexemplary form of novel, foldaway seating arrangement 10 shown thereinis arranged for use in cooperation with railing 12 usually provided inarenas, auditoria and the like as mentioned previously. The railing 12,therefore, usually includes a number of standards or supports 14 andhorizontal runs 16. Usually the standards and runs 14, 16 are fabricatedfrom steel pipe and suitable fittings (not shown) provided for exampleto connect sections of the pipe. However, railings of other constructionare obviously contemplated.

The seating arrangement 10 proper includes a platform or table 18 havingfoldable legs 20 and 22 adjacent the front and rear edges thereofrespectively. The legs, 20, 22 in this example are provided withconventional hardware indicated generally by reference character 24 of acollapsible nature. In this arrangement it is contemplated that a numberof the tables 18 be provided and distributed along the length or lengthsof the railing 12 as required for the anticipated excess crowds. Forconvenience in handling, each of the tables 18 is provided in suchlength to accommodate in the order of about six folding chairs 26. It isto be understood, however, that the number of chairs 26 supported on agiven table 18 can be varied as desired, along with the length of thetable. Desirably the chairs 26 are positioned along the length of thetable or platform 18 and prevented from displacement across the topsurface 28 thereof by means of an apertured strip 30 secured to the top28 of the table and extending in this example along the rear lateraledge portion of the table 18. The strip 30 is provided with a number ofapertures 32 which are spaced to receive in this example the lower endportions 34 of the rear chair legs 36. Desirably the apertures 32 extendentirely through the safety strip 30 so as not to cause the chair 36 tobe tilted forward.

Railing engaging means including a number of 2-positioned brackets 38are secured at spaced intervals along the front edge portion of thetable 18 as better shown in FIGURE 1. In this example, three suchbrackets are so utilized, although the number obviously can be varied,depending on the application of the invention. Each of the brackets 38includes an angular or bracket section 40, whereby the brackets 38 aresecured to the table 18, and a first arcuate section 42 forcomplementary engagement over the adjacent top surface of the lower run16A of the railing 12. It is contemplated of course that a shape otherthan that shown can be imparted to the brackets section 42 dependingupon the given cross sectional configuration of the railing run 16A. Thebrackets 38 as thus far described thus prevent the table 18 from beingdisplaced rearwardly of the railing 12 and from consequently blockingthe remainder of aisle 44. It is also contemplated that sufficientstructural stength can be imparted to the brackets 38 or that additionalnumbers thereof can be provided as desired to support entirely the frontportion of the table 18, in which case the front legs 20 thereof can beeliminated, where permitted by applicable codes.

As better shown in FIGURE 3 of the drawings the 2- positioned bracket 38has an additional function. When the sitting arrangement 10 is not inuse, the table 18 is stored at the location of its use by securing thetable 18 to the railing 12. In the latter arrangement of the inventionthe bracket 38 is provided with an additional arcuate section 46adjacent the outer end portion thereof so that the table 18 with itslegs 20, 22 now in their folded positions,

can be suspended from the uppermost run 16B of the railing 12. It willbe seen in the arrangement shown that the table 18 can be thus stored onthe railing 12 on either the front or rear side thereof. In any eventthe table 18 when in its stored position as shown in FIGURE 3 offerslittle or no obstruction to the adjacent aisle 44. With this arrangementonly the folding chairs 26 have to be conveyed from and to additionalstorage facilities therefor. The bulkier platforms such as the platform18, however, can be secured along the length of the railings such as therailing 12 at the respective locations of their subsequent use.

To prevent inadvertent removal of one or more of the tables 18additional, cooperating railing engaging means including brackets 48 canbe secured along the rear edge portion of the table 18 is accordancewith another feature of the invention. The brackets 48 are of singleposition construction and include base section 50 for securancedesirably to the underside of the table 18 and an arcuate section 52adjacent the outer or free end of the brackets 48. The brackets 38 and48 desirably are fabricated from a resilient structural material such ashot rolled steel so that, when the brackets 38 are initially engagedover the top run 16B of the railing 12, the cooperating brackets 48 canbe snapped under the adjacent surfaces of the lowermost run 16A. Thisproduces a snapped-in clamping action to secure or suspend the table 18in its stored position against the railing 12. The arcuate sections 46and 52 of the brackets 38 and 48 respec tively can be varied to suit theconfigurations of railing runs 16A, 16B as described previously inconnection with arcuate sections 46 of the brackets 38.

In the event that the brackets 38, 48 are not suflicient- 1y resilientor that the cross sectional configuration of railing runs 16A, 16B donot lend themselves to the aforedescribed, co-operative snap action ofthe brackets, at least the lower brackets (as viewed in FIGURE 3) aresecured to the table 18 with wing nuts or thumb screws 54 to permitloosening of the brackets 48 and fitting around the railing runs, suchas runs 16A, 16B followed by tightening the thumb screws 54 to clamp thetable against the adjacent portion of the railing 12.

With reference now to FIGURES 4 and 5 of the drawings a modified form10' of my seating arrangement is illustrated wherein similar referencecharacters with primed accents refer to similar components of FIGURES 1to 3. In the open or operative position (not shown) of the seatingarrangement 10' the disposition of the various components issubstantially as shown in FIGURES 1 and 2 of the drawings. Thus, thetable 18' in its unfolded or operative position is stabilized orsupported as desired at the lowermost railing run 16A by railingengaging means including arcuate section 42' of each 2-position bracket56. In the stored position of the table 18' the brackets 56 cooperatewith additional railing engaging means including brackets 58 to spacedlysecure the table 18 to railing runs 16A and 16B. In furtherance of thispurpose the brackets 56, 58 are provided with intermediate elongatedsections 60 and 62 respectively to space their rail engaging sections 46and 52' farther outwardly from the table 18 in comparison with thebrackets 38, 48 of the table 18 in FIGURES 1 to 3. The brackets 56, 58otherwise function in much the same manner as the brackets 38, 48described above with reference to FIG- URES l to 3.

This outward spacing of the table 18' from the railing 12' affords astorage space 64 into which those chairs 26 which are utilized with agiven one of the tables 18 are inserted in their folded positions asillustrated. The chairs 26' when thus stored are supported and thusprevented from sliding downwardly from between the railing 12' and thejuxtaposed table 18' by means of an elongated supporting strip 66secured by suitable means along the lower lateral edge 68 of the table18', as viewed in FIGURES 4 and 5.

The form of my seating arrangement of FIGURES 4 and 5 presents the addedadvantage of providing storage for both the platforms 18' and thefolding chairs 26 used thereon at each location of their use. In thefoldaway position of the platform 18' and chairs 26 a very compactarrangement is obtained which does not introduce any substantialobstruction into the adjacent aisle.

In FIGURES 6 to 9 of the drawings still another form 110 of my novelseating arrangement is disclosed, which is compact and still more easilymanipulated between the operative and foldaway positions thereof. Theseating arrangement 110 includes a platform 118 arranged to cooperatewith a permanently installed railing 12' described before. The table orplatform 118 is likewise provided with folding legs 120, and 122, whichare similarly braced by collapsible brackets 124. Foldable seating means125 are hingedly or foldably joined to the platform 118.

One form of such foldable seating means includes a foldable bench 126hingedly secured at 127 to an up right strip 128 secured along the upperrear edge portion of the table 118. The foldable bench 126 furtherincludes a seat portion 129 hinged to its back panel .130 at 131 and aleg portion 132 hinged to the seat portion 129 at 133. The hinges127,131, and 133 are sufficiently strong to support the anticipatedweight and thus the hinges, particularly hinges 127 and 131, can befurnished in the form of conventional piano type hinges.

To stabilize the foldable bench 126 in its upright position as shown inFIGURES 6 and 7 a stabilizing strip 134 is mounted on the table 118 andis provided with a groove 135 into which the lower end portion of theleg panel 132 is inserted. Desirably the foldable seating means panels129, 130, 132 andthe stabilizing strip 134 extend along the entirelength of the platform 118. Although the seating means 125 has beenillustrated as a continuous bench 126 coextensive with the platform 118,it is also contemplated that the seating means 125 can take the form ofdiscrete folding chairs of similar construction by interrupting thepanels 129, .130, 132 thereof as denoted by chain lines 136 to provideindividual chairs 137, as better shown in FIGURES 6 and 8. It is alsocontemplated that conventional folding chairs, .such as either of thetypes shown in FIGURES 4 and 5 can be hingedly or foldably jointed tothe platform 118.

Along the front edge portion of the platform 118 railing engaging meansincluding a number of pivot brackets 138 are secured. In this exampleeach of the brackets 138 includes an O-clamp section 140 which isrelatively closely fitted around the adjacent portion of the lowermostrailing run 16'A. The brackets 138 thus stabilize the platform 118 toprevent displacement from the railing 12. If desired the front legs 120can be removed as discussed in connection with the legs of FIGURES 1 to3 of the drawings. In the present arrangement the brackets 138 arepermanently and pivotally joined to the railing run 16'A so that theplatform 118 can be pivoted from its operative horizontal position asshown in FIGURES 6 and 7 to its vertical or storage position as shown inFIGURES 8 and 9.

Before thus folding away the platform 118, however, the seat means 125which are hingedly and permanently joined to the platform 118 in thisexample, are folded downwardly against the upper surface'of the platform118. This is accomplished by raising the leg panel 132 and seat panel129 upwardly along the paths denoted by arrows 142 and 144 respectively,which first displaces the lower end ofthe' leg panel 132-from thestabilizing strip 134 and then finally folds the panels 129, 132 againstthe upper front portion of the back panel 130. The seat means 125 withthe panels 129, 132 thus folded, are then folded downwardly along thepath denoted by arrow 145 such that the seating means 125 assumes afoldedposition against the supporting platform surface 119 substantiallyas shown in FIGURES 8 and 9 of the drawings. Following this operationthe platform 118 is pivoted about 6 clamp sections 140 to the foldawayposition of the seating arrangement as shown in FIGURES 8 and 9 of thedrawings.

To retain the foldaway seating arrangement 110 in its storage position(8 and 9) additional railing engaging means including cooperatingbrackets 148 are secured adjacent the rear of the platform 118 tolateral platform extension 149 by means of their base sections 150. Thebrackets 148 are further provided with complementary rail-engagingsections 152 which, owing to the resiliency of the brackets 148 and base138, can be snapped over the adjacent upper surfaces of the uppermostrailing run 16'B. However, to prevent inadvertent rem-oval of theseating arrangement 110, when in its foldaway position, complementaryclamp sections 154 can be bolted or otherwise secured to the snap oversections 152 to complete an O-clamp section thereat. It is alsocontemplated that all of the clamp sections 140 and 154 can be omittedand that the platform 118, when not in use, can be merely suspended fromthe top railing run 166 by reversing the railing engaging means 148 tothe position of the railing engaging means as shown in FIGURES 3-5. Theplatform legs and 124 are subsequently folded as better shown in FIGURE9 of the drawings.

When the seating means are provided in the form of individual foldingchairs 137, the cooperating railing engaging means brackets 148 can besecured inwardly of the chair supporting strip 128 and between adjacentchairs, as denoted by chain-outlines 156 thereof in FIG- URES 6-8. Inthis alternative the platform extension 149 can be omitted.

The height of the chair means supporting strip 128 above the surface ofthe platform 118 desirably is sufficient to permit folding of theseating means 125 to a substantially parallel array of its panels 129,130, 132. In addition the brackets 138 and 148 desirably are providedwith intermediate section-s 160 and 162 (FIGURE 9) respectively toprovide sufiicient space 164 between the railing 12 and the platform 118to accommodate the folded seating means 125.

- The last-described form of my foldaway seating means 110, in additionto storaging a large number of such seating arrangements such as theplatform 118 and the associated seating means 125 at their respectivelocations of intended use, considerably reduces the time and laborrequired in setting up and folding away the seating arrangement 110. Ina relatively large arena or auditorium the total savings in such timeand labor are enormous, not to mention the savings involved ineliminating separate storaging or warehousing of conventional temporaryseating arrangements.

It is to be understood, of course, that certain features of my inventioncan be interchanged or transposed among the various forms of my foldawayseating arrangements. For example, the railing engaging means of FIGURES6-9 can be employed in the seating arrangements of FIG- URES l-3 orFIGUR'ES 4-5, and conversely, the railing engaging means of FIGURES 4-5can be used in the organization of FIGURES 6-9, as desired in aparticular application of the invention.

From the foregoing it will be apparent that novel and efficient forms offoldable seating arrangements have been disclosed herein, part or all ofwhich are storagea'ble on location.
